User reviews

Be perfect if it also labeled the opening name

Great app, but please provide the names of the openings

Itโ€™s stable and does what it says

Exactly as described - a chess opening explorer. It works and I am learning heaps from it.

Great app

I use this app to help learn chess movesโ€ฆ I wish however it could tell me what the actual openings were called and the defenses I play so I can better get a grasp on what Iโ€™m playing and my play style!!

Itโ€™s great

When I come back from my tournament then I can analyze it so that I can see how good or bad I played

Label all columns

Very useful app, but you need to label all of the columns in the move table. If that number to the far right is a percentage, I need to know what is it the percentage of?!

Response from developer

Hi. if there are a total of 10 games on a row and 2 are wins, 6 are draws and 2 are losses, the points scored are 2 for the wins, at a half point each, 3 for the draws, so a total of 5/10. percentage is .50 or 50% win ratio
